I've written about the importance of sleep before, but there is new research linking sleep-deprivation to Alzheimer's disease. In the October 24, 2009 issue of "Science News," it's reported that not getting enough sleep could lead to plaques in the brain which lead to the death of neurons and to symptoms of Alzheimer's.

Lack of sleep may also lead to:

Increased hunger

Insulin resistance

Higher risk of Type 2 diabetes

Increased obesity

Higher risk of heart disease

Increased inflammation

Greater chance for hardening of the arteries

Greater chance for rheumatoid arthritis

Decreased reaction time and accuracy

Immune system impairment

Declines in memory

Decline in judgment

Brain chemical changes that can lead to depression

Higher risk of metabolic syndrome

Increase in irritability, impatience,and moodiness

Higher risk for hypertension

Greater risk for accidents and mistakes

Increased use or abuse of alcohol, tobacco, and drugs

There are techniques you can use to combat sleep problems:

Keep a regular schedule

Avoid caffeine four to six hours before bed

Avoid alcohol, tobacco, and heavy meals before sleep

Get regular exercise

Keep your bedroom dark, quiet, and cool

Sleep is important, and while scientists can't fully explain how it works to restore the body and brain, they know that it does. So get your 7 to 8 hours a night. Keep in mind that younger children need more. Children 3-6 years of age should get 11-12 hours of sleep. Those aged 7-12 should sleep 10-11 hours each night. And 12-18 year-olds should be sleeping 8-9.5 hours a night.
